the following 2 items:
1. Battery power level
2. Power source (battery or AC supply)
The battery power level represents the percentage of the remaining
battery power. The power source indicates whether power is coming
from the battery or the AC power supply. If the battery power level
drops under 15 percent, the Braille Sense Plus B32 will display the
battery status on the Braille display, and it will announce (through the
speakers) that the battery has less than 15 percent of its power left.
If the battery power level falls below five percent, the Braille Sense
Plus B32 will give you a warning indicating that your battery power
level is under five percent, and the Braille Sense Plus B32 will be
automatically turned off in one minute, unless you connect the Braille
Sense Plus B32 to an AC power supply.
Let’s explore the detachable battery pack. When the Braille Sense
Plus B32 is shipped, you will find the battery pack is not installed in
the Braille Sense Plus B32. This is done to prevent damage during
shipping. When you insert this battery pack in to the Braille Sense
Plus B32 for the first time, the unit may display an inaccurate battery
power level. Before using the Braille Sense Plus B32 for the first time,
please charge the battery for six hours. If you need to use the unit
during the initial recharge, the unit should be connected to the AC
power supply for at least seven hours in order to fully charge the
battery. When you remove the battery from the Braille Sense Plus
B32, make sure your unit is turned off; especially when the AC power
supply is not connected to your unit. Otherwise, you will lose all of
your data that is stored in RAM. If you remove the battery, and do
not have the Braille Sense Plus B32 hooked up to the AC power
supply, your data that is stored in RAM will remain for only about an
hour. In order to keep your data that is stored in RAM, the Braille
Sense Plus B32 must be connected to an AC power supply or battery
pack within an hour; otherwise the data that is stored in RAM will be
lost.
